Do you monitor loading and unloading processes of bottom loading tank trucks?

Bottom loading of road tank trucks is characterized by simultaneous loading of fuels into closed tanker compartments with high loading rates and no possibility of manual supervision. To prevent hazardous spills, the accumulation of electrostatic charges and the evaporation of emissions, an emergency shut-off system, supervised grounding, and vapor collection is mandatory by law and to ensure safe loading processes.

The Overfill Prevention Controller EUS-2 is the central part of the overfill prevention system according to European VOC Directive 94/63/EC and American API RP 1004. EUS-2 monitors the level sensors at the tanker compartments, the truck grounding and the vapor recovery connection. The filling process is interrupted immediately at the loading gantry, if a critical situation is detected.

BENEFITS

  • Plain text messages display in mother tongue of the operator
  • Opening of the housing during operation in hazardous areas is allowed
  • Intuitively operation of configuration menu via innovative joystick navigation
  • Serial data interface (Ex ib) for connection with the TExi data bus (intrinsically safe data bus by Timm Elektronik)
